TIPPING HAN D.-'.1OOL.

Specification of Letters Patent.

PatentedSept. 2, 1919.

Application filed June 11, 1918. Serial No. 239,371.

Lawrence, in the county of Essex and'State of Massachusetts, haveinvented certain new and useful Improvements in Tipping Hand- Tools, ofwhich the fOllOWing is a specification.

This invention relates to means for providing shoe lace ends withstiffening tlps, and refers particularly to tools to be operated by handfor firmly clenching the tips onto and around the lacing.

The object of the invention is to provlde a simple and easily operatedhand tool having ample power to clench the tips immovably on the lacingand to do the work accurately and uniformly.

To this end, the invention consists in the construction and combinationof parts of the tool substantially as hereinafter :described andclaimed.

Of the accompanying drawings:

Figure 1 is a side elevation of the tool.

Fig. 2 is an end view from the left of Fi 1.

Fig. 3 represents a section on line 33 of Fig. 2.

Figs. 4, 5, 6 and 7 are detail views on a larger scale illustratingsuccessive operations hereinafter described.

The tool comprises a pair of lever members crossing each other andpivotally connected at 12 and having handle portions 13 and relativelyshort arms 14. The handles 13 are normally held apart by a suitablespring 15 to a limit determined by cooperating shoulders 16, 17.

The intermeshing or interengaging dles are carried by the short arms 14of the lever members. The female die 18 has lugs 19 straddling the endof one of the lever arms 14 and pivotally or hingedly connected theretoby a pin 20 preferably headed at both ends like a rivet. The other endof the member 18 has a deep recess 21 the bottom of which issemi-circular in contour. The male die 22 has lugs 23 straddling the endof the other lever arm 14 and pivotally or hingedly connected thereto bya pin 24, similar to pin 20. The other end of the member 22 is reducedto form a rib 25 with shoulders 26. Said rib is so proportioned as tosection the grooved edge 27 of said rib coacts with the curved bottom ofrecess 21 in presenting a substantially tubular space. In other words,the stop shoulder structure described accurately limits the closing oroperative movements of the dies and prevents the sharp edges of rib 25from being injured or cutting into and marring the rounded bottom ofrecess 21. Since the cooperating stop members are carried by the diesthemselves, it is easy to re-fitthe device for use after wear, becausethe bottom of the recess 21 can be re-shaped, and the grooved edge ofrib 25 also l e-shaped or sharpened, and then stop shoulderorshoulders26 reduced or ground to enable the tip forming surfaces toagain accurately cooperate.

"The stiffening tips a-may be of any of the well-known materials,longitudinally U- shaped and having a row of perforations to forminwardly-extending tongues to enter the lacing material 6 as usual.

In operation, the user of the tool first places the end of the lacing ina tip a while the latter is in the form shown in Fig. 4 and pinches thetip to close it (see Fig. 5) sufficiently on the lacing to .cause it toremain there until inserted between the dies of the tool as indicated inFig. 6. The handles 13 are then moved toward each other until furthermovement is arrested by the stop shoulder structure of the dies. Thiscauses the sharp edges of the die rib 25 to ride down outside the edgesof the tip a and close them, one usually in advance of the other, theproportions of the handles 13 relatively to the arms 14 which carry thedies being such that ample force can be brought to bear to finally rollthe tip tightly around the lace end, (Fig. '7). During the closingmovement of the tool, the dies slide freely toward each other owing totheir pivotalconnection with the arms 14. When hand pressure on theblanks 13 is re leased, the spring 15 parts them and causes the dies toslide apart far enough to release the tipped lacing. The stop shoulders16, 17, however prevent such opening movement as to remove die rib 25entirely from die recess 21, these parts remaining in suflicient(preliminary pinching toward the ientlydone by hand, it can be easilyefiectgether.

'vided by the grooved edge I that, first,

ed by inserting-the edges of the tip a, While in the Fig. 4 position, inthe space between the outer shoulder 26 of die 18, and then closing thedies so. that said shoulder 26 and opposing portion of die 18 will pinchthe edges of the tipto- It is easy to so hold the parts and manipulatethe tool that one edge of tip a is closed in more than the other edge.

It will therefore be clear that I have provided a tool of thecharacterdescribed having-two clenching portions, viz: the closing jawsprovided'by the outer shoulder 26 of die 22 and the opposing surface ofdie 18, and the shaping or collapsing surfaces pro- 27 of die 22' andthe opposing curved bottom of recess 21.

This double function results from the fact the dies are pivoted inaccessible positions to the outer faces of the short arms 14:, and,second, the shoulder 26 is Copies of thispatent may be obtained for fivecents each, by addressing the. Commissioner of Patents,

and the opposing edge formed on the outer, exposed, surface of die 22Where it is readily accessible for the lateral introduction of thelacing and tip for the preliminary pinching or closing ustdescribed.

It is to be understood that I do not limit myself to the operationexactly as described. Instead of placing the lacing and tipin theposition indicated in Fig. 7 they may be inserted with the roundmid-wldth portion of J the tip opposite the grooved edge 27' of the maledie so that in operation the edges Will said recess to provide aclenching portion,.

the outer exposed surface of one of the dies being provided with ashoulder to coact With a portion of the other die to provide preliminarypinching members in accessible positions.

In testimony whereof I have afiixed my 7 signature.
